FAQ
Frequently asked questions
What can affect my PSA test results?
Several factors can influence PSA levels, including recent ejaculation, prostate infections, urinary tract infections, and certain medical procedures. Some medications may also lower PSA levels. It is important to inform your healthcare provider about any such factors before testing.
Do I need to fast before a PSA test?
Fasting is not typically required for a PSA test. However, some laboratories may have specific instructions, so it is best to check with the lab before your appointment.
How often should I get a PSA test?
The frequency of PSA testing depends on your age, risk factors, and discussions with your healthcare provider. There is no one-size-fits-all schedule, and recommendations vary among medical organizations.
Can a high PSA level mean I have prostate cancer?
A high PSA level does not necessarily mean you have prostate cancer. Many benign conditions, such as an enlarged prostate or prostatitis, can also raise PSA levels. Further testing is often needed to determine the cause.
